No. 143,650 2 Claims. (Cl. 24--225) This invention relates to improvements in fasteners for clothing in general and has particular reference to hook and eye fasteners for furs, fur coats and other clothing, partly or wholly of fur, natural or artificial.

The fasteners, hitherto and at present, used by furriers and traders of fur clothing are not wholly satisfactory; hook fasteners are unreliable in that, they are apt to fail and allow the fur garment to open when the wearer is moving; it is difiicult to operate several hook fasteners arranged one above the other as the operation of closing one hook in the series unintentionally may cause closed hooks in the series to open, particularly when the wearer has to bend down to close the lower books of a long fur coat; and spring hooks of known kinds that lie deep in the hair of the for are apt to cause the hair to be damaged or destroyed.

To avoid these disadvantages, buckle-like positively engaging fasteners have been used, but if such fasteners are to be closed quite safely, considerable force has to be exercised, both for the closing and the opening, and this introduces a risk of the hair around the fasteners being clipped into the fastener and being badly damaged.

The object of the present invention is to provide a fastener, comprising a hook and an eye, that avoids the above mentioned disadvantages, reduces the risk of damage to fur clothing, improves the security with which fur clothing can be maintained in place and is superior to buckle-like fasteners at present in use.

The invention consists of a hook fastener having a perforated base plate; a projection on the base plate curved to form a book; a channel on the inside of the projection; a curved blade spring, one end of which is attached to the free end of the projection while the other end slides in that part of the channel adjacent to the base plate and a. pin mounted in the base plate to project towards the path of the curved blade spring that is parallel to the base plate.

The invention may be carried into effect by many different arrangements and the following description is to be regarded as being given only by way of example.

In the drawing accompanying this complete specification:

FIGURE 1 is a side elevation, partly in section, of a fastener in whichthe eye portion is shown disengaged from the hook portion;

FIGURE 2 is a front elevation of the hook portion shown in FIGURE 1.

The eye E for the hook may be of any convenient shape e.g. may be a ring, as shown in the drawing or a loop of any shape or configuration, having a part to be attached to clothing, e.g. fur, by sewing, riveting or by other means and may be made of plastics or metal.

The hook, as shown in FIGURES 1 and 2 of the drawings, consists of a metal or plastic base plate 1, having several holes 2 to enable it to be attached to clothing, e.g. fur or other material by sewing, riveting or the like.

The base plate 1 has a projection 3, formed integrally with it or attached thereto by welding or riveting, the projection 3 being bent over to dorm a hook having a free front end that is substantially parallel to the base plate 1.

The inner side of the free end of the projection 3 has a recess or channel 4, that is of box-shaped cross section, to receive the ends of the blade spring 5, the width of which corresponds with the width of the channel 4.

The end of the spring 5, located in the channel 4, is attached to the free end of the projection 3 by the rivet 6,

and the dimensions of the channel 4 are such as to prevent any twisting of the spring 5 about the rivet 6.

The spring 5 is curved and turned so that its median part projects towards the base plate 1, the free rear end '7 of the blade spring 5, also being guided in the remote end of the channel 4 so as to prevent any twisting of the blade spring 5 Whilst allowing of a sliding movement of the end 7 in a longitudinal direction along the projection 3.

The reduced end portion 9 of the pin 8 is inserted into a hole in the base plate 1 and is secured in place by riveting, the pin 8 being located to be opposite to the median part of the blade spring 5 so that the end of the pin 8 is in close proximity to the part of the blade spring 5 that is parallel to the base plate 1.

To improve security of the fastening, as shown in FIG. 1, the median part of the blade spring 5, in proximity to the end of the pin 8, may be provided with a cup shaped recess 10, to be engage-d by the end of the pin 8 that is made substantially hemispherical to co-operate with the recess.

To reduce the friction between the free rear end 7, of the blade spring 5 and the channel 4, the free end 7 cf the blade spring 5 is slightly curved or bent inwardly, the radius of curvature of the bend being smaller than the radius of curvature of the adjacent portion of the channel 4.

In use it is sufficient to place the eye e.g. the ring E, between the end of the pin 8 and the median part of the spring 5 and pull. By such a movement the force of spring 5 is overcome and the free end 7 slides along the channel 4 to provide a narrow gap, sufficiently wide to allow the ring E to pass.

When the ring E is engaged by the hook, the ring passes to the rear portion of the member 3, ie the part adjacent to the base plate 1, so that spring 5 is not stressed during use.

What is claimed as my invention is:

1. A hook fastener device for fur garments, comprising a perforated fiat base plate having a plurality of spaced [holes tor attaching the plate to a garment, a projection on the base plate curved to form a hook, there being a channel on the inside of said projection, a curved blade spring having one end fixedly secured to the free end of said projection and another end slidable in that part of the channel adjacent the base plate, saidspn'ng having an intermediate convex portion spaced from said plate, 'a pin mounted in the base plate and normally engaging said convex portion, said other spring end, said convex portion and said plate defining a closed, yieldab le and separable loop portion, a ring'member adapted to be secured in looking engagement in said separable loop portion without contacting the fur and meansfor securing said ring to a garment.

2. The invention as claimed in claim 1, wherein said convex portionis formed with a recess and the free end of the pin is rounded and engages with said recess in the blade spring.
